Mobile security

An additional layer of protection for mobile transactions
Discover® Tokenization

Discover® Tokenization sends sensitive PAN data to a more secure location where it is authorized by issuers and acquirers. It is then replaced with a unique token number for each transaction, making it meaningless to anyone unauthorized to access it.


Fraud management tools for issuers and acquirers

Discover Account Incident Manager (AIM) is a web portal that provides a single point of access to real-time incident information. AIM provides up-to-date details and activity for each case and proactively alerts users as each case changes.
